Who Is Kacy Byxbee?
Kacy Byxbee works behind the camera. Her name appears in the costume and wardrobe department credits of Hawaii Five-0, the CBS action series that ran for ten seasons. She became publicly known mainly because of her relationship with Scott Caan, who played Detective Danny “Danno” Williams on the show.
She has never been a famous actress, singer, or influencer. Some websites claim she played a doctor on Hawaii Five-0 or built a music career. Those claims have no support in IMDb credits or in news coverage from outlets such as E! News and Us Weekly, so this article does not repeat them.
Early Life and Family Background
Very little about Kacy Byxbee’s childhood is publicly confirmed. She has not given long interviews about it, and no major outlet has published a verified account.
One biography site says she was born in Los Angeles to Charles Byxbee, who is linked to a development company, and Kelly McConnell Byxbee, and that she has two sisters named Karlyn and Kennedy. I found these details on only one site, so I treat them as unverified.
Her birth date is also unclear. The most repeated date is January 24, 1977, which would make her 49 in 2026. However, other pages give birth years in the 1980s and 1990s, and one age-focused article notes that the 1977 year has not been confirmed by a strong source. If you see an exact age stated as fact, be careful.
Kacy Byxbee Career
Kacy Byxbee’s career is in costume and wardrobe work for television and film. This is the best-documented part of her life story.
Work on Hawaii Five-0
IMDb lists her in the costume and wardrobe department of Hawaii Five-0. Across different episode pages, her credit appears as costume supervisor, with some entries also showing assistant roles, including uncredited ones. One secondary biography says she worked on 69 episodes between 2011 and 2014, but I could not verify that exact number from a primary source, so treat it as approximate.
Costume Supervisor or Costume Designer?
This is a point many websites get wrong. Most describe her as a “costume designer” or even a “model.” IMDb shows “costume supervisor,” which is a different job. A costume designer creates the overall look of a production. A costume supervisor manages the wardrobe, keeps track of outfits, and makes sure continuity is correct from scene to scene. Both are real, skilled roles, but the titles are not the same. Other credits mentioned by a 2026 profile include Somewhere and All at Once, though I could not confirm further details about them.
Writing and Blogging
Some articles say she writes a parenting and lifestyle blog called Kacy Has Freckles and has written for a motherhood website. This was reported in an entertainment explainer, but I could not open the blog myself, so I list it as reported rather than confirmed.
Kacy Byxbee and Scott Caan: Relationship Timeline
Their relationship is the main reason people search for her name. Because both keep their private life quiet, the timeline has gaps. Here is what reliable coverage supports.
| Year | Event |
|---|---|
| Early 2010s | They met while working on Hawaii Five-0. Sources give 2010, 2011, or 2013, so the exact year is unconfirmed |
| January 2013 | Scott Caan briefly mentioned a live-in girlfriend on Chelsea Lately and joked she deserved a medal for putting up with him |
| June 2014 | Reports said the couple was expecting their first child, and Caan’s representative confirmed it to Us Weekly |
| July 9, 2014 | Daughter Josie James Caan was born, as reported by E! News |
| June 2016 | The couple was photographed at a Father’s Day dinner with Scott’s father, actor James Caan |
| 2023 | Around the premiere of Alert: Missing Persons Unit, Scott said on TV that they had a baby about two months old |
| 2025–2026 | Getty Images captions place the couple at Broadway openings and screenings in New York, including November 2025, January 2026, and March 2026 |
Josie’s middle name is widely understood to honor Scott’s father, James Caan, though the couple has not explained it themselves.
Are Kacy Byxbee and Scott Caan Married?
The honest answer is that it is unclear. Early news from 2014 called her his girlfriend. Scott Caan’s Wikipedia page now lists her as his spouse, and some articles say they are married. Other articles say they are not legally married and chose that on purpose. None of these claims comes with a marriage record or a public statement from the couple.
For that reason, the safest description is “longtime partner.” A magazine that claims a wedding date or location is guessing, because no verified details exist.
Children and Family Life
Josie James Caan, born July 9, 2014, is the couple’s first child and is confirmed by E! News and Us Weekly. For the second child, the only source I found is a secondhand report of Scott’s TV remark in early 2023. Websites that give a name, gender, or birth month for that child contradict one another, so I have left those details out.
The couple has kept their children away from public events and social media. This is likely why the public knows so little.
What Is Kacy Byxbee Doing in 2026?
There is no confirmed major film or TV project for her in 2026. Recent public appearances appear to be red-carpet and theater events with Scott Caan. One 2026 profile also states that reliable information about her current work is limited, and that matches my own findings. Anyone claiming to know her current job or home address is not working from verified information.
Kacy Byxbee Net Worth
No trustworthy source has confirmed her net worth. Some websites estimate $1 million to $10 million as of 2026, but they do not show how they calculated it. Treat this as a rough, unverified estimate and not as a fact.
Common Myths About Kacy Byxbee
| Claim You May See | What the Evidence Shows |
|---|---|
| She is an actress on Hawaii Five-0 | No. IMDb lists her in the costume department |
| She is a famous model or singer | No reliable source supports this |
| She has a confirmed birth date | No. January 24, 1977 is repeated often but not verified |
| They had a Hawaii beach wedding | No credible report confirms any wedding |
| She has a large Instagram following | No verified public account was found |
How This Was Researched
I researched this biography by checking IMDb credit pages, E! News and Us Weekly reporting, Getty Images event captions, and several recent profile articles. I compared the competing biographies and found that many repeat unverified birth dates, give her wrong job titles, or invent acting roles. This article tries to fill that gap by clearly labeling every detail as confirmed, reported, or unconfirmed. I have no personal connection to Kacy Byxbee and used only public information.
